6. Allow two minutes for the sensor to
warm up, after which the flashing
probe light and sound indicator will
idle at approximately 1 click per
second.
7. Test operation by quickly touching the
probe tip to the top of the calibration
reference bottle (make sure sticky
label is removed). The unit should
respond with a rapid flash rate and
sound verifying correct operation and
optimum sensitivity. If the unit does
not respond correctly, see Section 3.1.
2.7. Checking for Leaks
! SAFETY WARNING: For your safety, DO
NOT use this device to detect for leaks of
refrigerants which are rated as
combustible/flammable gases (e.g.,
ASHRAE A2- or A3-rated refrigerants).
1. Set the range switch to the
appropriate range to ensure
maximum sensor life. If the leak size
is unknown, start at the Large leak
setting. This protects the sensor if a
large amount of gas is present.
! IMPORTANT: Exposing the sensor
to large amounts of refrigerant or
holding the probe over a leak for a
long period of time will significantly
shorten sensor life.
2. Check for leaks in a logical
progression through the entire
system.
3. If surfaces are dirty or wet, wipe
them off with a clean, dry cloth to
reduce filter clogging and extend
sensor life. DO NOT allow the unit to
draw in moisture. Use of the supplied
rubber probe tip helps prevent
moisture from being drawn into the
